Ajax

First released in 1987 by legendary Japanese game publisher Konami, Ajax (also known as Typhoon in some regional markets) is a fast-paced vertical scrolling shooter arcade game that quickly became a staple of 1980s arcade halls worldwide. Set in a fictional near-future where a rogue global terrorist organization has seized control of military outposts across land, sea, and air, players take on the role of a fighter pilot tasked with neutralizing enemy forces across 8 challenging stages. Unlike many shooters of its era, Ajax stands out for its smooth 8-bit pixel animation, dynamic background design that shifts from desert canyons to ocean battleships and mountain strongholds, and a punchy chiptune soundtrack that perfectly matches the high-stakes action. The game supports both single-player and 2-player co-op modes, letting friends team up to take down waves of enemy fighters, ground turrets, armored tanks, and massive stage bosses. Each playthrough offers a range of upgradable weapons,

Game Guide

Mastering Ajax’s fast-paced action is easier with these key tips to help you beat all 8 stages and set high scores. First, familiarize yourself with the core controls: use the 8-way joystick to move your fighter across the screen, the first button to fire your primary weapon, and the second button to deploy a screen-clearing bomb that destroys all small enemies and deals heavy damage to bosses. For new players, prioritize picking up homing missile power-ups first, as these automatically track enemy targets and let you focus on dodging incoming fire instead of aiming. Spread shot power-ups are ideal for clearing large waves of incoming fighter formations, while laser beams deal the highest damage to heavy armored targets like stage bosses and ground battleships. Always save at least 1 or 2 bombs for boss encounters: each boss has a clearly marked weak point (such as the top cannon of the first stage tank boss, or the bridge of the second stage naval warship) that you should focus fire on while dodging their projectile attacks. In 2-player co-op mode, split responsibilities to cover more ground: have one player focus on clearing airborne enemy fighters, while the other takes out ground turrets and low-flying targets to avoid being hit from below. Keep an eye out for hidden transport planes that appear briefly mid-stage: destroying them drops a rare full power-up and extra life bonus. Avoid hugging the edges of the screen, as enemy fighters often spawn off-screen and can crash into you before you have time to react. Finally, remember that clearing a full formation of enemy fighters without missing any gives you a 10,000 point bonus, which unlocks extra lives every 50,000 points to help you progress through later, harder stages.
